Specificity and Mechanism of Protein Kinase C Activation by sn-1,2-diacylglycerols.
Ganong BR, et al.
Proceedings of the National Academy of Sciences of the USA, 83, 1184-1188 (1986)

FEBS letters, 589(11), 1272-1277 (2015-04-12)
Diacylglycerol kinase (DGK) η plays important roles in various patho-physiological events such as oncogenesis. In this study, we performed an enzymological characterization of DGKη splice variant 1 (DGKη1). The Km value for diacylglycerol was 0.14 mol%. Intriguingly, the Km value...

Leukotrienes (LTs) are autacoids derived from the precursor arachidonic acid (AA) via the action of five-lipoxygenase (5-LO). When inflammatory cells are activated, 5-LO translocates to the nuclear membrane to initiate oxygenation of AA released by cytosolic phospholipase A2 (cPLA2) into...
E G Lapetina et al.
The Journal of biological chemistry, 260(3), 1358-1361 (1985-02-10)
The ability of exogenous sn-1,2-diacylglycerols and analogs to function as bioregulators of protein kinase C in human platelets was investigated. The activation of protein kinase C in platelets is indicated by specific phosphorylation of a 40,000-dalton protein. Dihexanoylglycerol, dioctanoylglycerol (diC8)...

The cell-permeable diacylglycerol, sn-1,2-dioctanoylglycerol (DiC8), is shown to mimic the effect of tumor promoting phorbol diesters on epidermal growth factor (EGF) binding and action in intact cells. DiC8 inhibited the binding of [3H]phorbol dibutyrate to A431 cell monolayers indicating that...

Decreased expression of diacylglycerol (DG) kinase (DGK) δ in skeletal muscles is closely related to the pathogenesis of type 2 diabetes. To identify DG species that are phosphorylated by DGKδ in response to high glucose stimulation, we investigated high glucose-dependent...
J G Ebeling et al.
Proceedings of the National Academy of Sciences of the United States of America, 82(3), 815-819 (1985-02-01)
Activation of cellular protein kinase C appears to be involved in the mechanism by which phorbol diesters induce differentiation of human myeloid leukemia cells (HL-60). Protein kinase C is thought to be physiologically activated by diacylglycerol derived from receptor-mediated phosphatidylinositol...

The activation of phospholipase C (PLC) is a conserved mechanism of receptor-activated cell signaling at the plasma membrane. PLC hydrolyzes the minor membrane lipid phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2], and continued signaling requires the resynthesis and availability of PI(4,5)P2 at the plasma...
Mathias Haag et al.
Metabolites, 2(1), 57-76 (2012-01-01)
Lipids, such as phosphoinositides (PIPs) and diacylglycerol (DAG), are important signaling intermediates involved in cellular processes such as T cell receptor (TCR)-mediated signal transduction. Here we report identification and quantification of PIP, PIP2 and DAG from crude lipid extracts. Capitalizing...
Maria Saliakoura et al.
Oncogene, 39(14), 2948-2960 (2020-02-09)
Enhanced prostaglandin production promotes the development and progression of cancer. Prostaglandins are generated from arachidonic acid (AA) by the action of cyclooxygenase (COX) isoenzymes. However, how cancer cells are able to maintain an elevated supply of AA for prostaglandin production...
Yuuna Kamiya et al.
Biochemistry and biophysics reports, 7, 361-366 (2016-07-20)
A variety of diacylglycerol (DG) molecular species are produced in stimulated cells. Conventional (α, βII and γ) and novel (δ, ε, η and θ) protein kinase C (PKC) isoforms are known to be activated by DG. However, a comprehensive analysis...
